3.5 UMTS-GSM Antenna Connector

The antenna connector allows the transmission of radio frequency (RF) signals between the modem and

an external customer-supplied antenna. The modem is fitted with a 50Ω, FME male coaxial jack.

The external antenna must be matched properly to achieve best performance regarding radiated power,

DC-power consumption, modulation accuracy and harmonic suppression.

3.6. GPS antenna connector

The antenna connector allows transmission of radio frequency (RF) signals between the modem and an

external customer-supplied antenna. The modem is fitted with a 50Ω, SMA female coaxial jack.

It is possible to connect 3.3v active or passive GPS antennas. In either case they must have 50 Ohm

impedance.
